Noctemburg is a mostly-subterranean city that stretches for considerable distance. It encompasses several distinct areas, some of which are almost completely isolated from the others. Its location and nature makes it an ideal home for certain types of beings thought of as supernatural in nature, especially certain Vampires who may be affected by sunlight. Because of this, the Vampire population is extremely high in some parts of the city.
It is well-known in many realms for its diverse population and convenient locale in relation to many other important destinations. Some important trade routes and business channels go through Noctemburg.
The area most commonly regarded as a 'red-light district' was where Dhiar first opened Phantasies, just across from a popular nightclub. Phantasies became a notable shop itself, in time, and was well-known by the time Dhiar left Noctemburg some years later.
